While we have some Pocket Wizards users here I have a couple of questions.
1: Can you fire a Canon 20D and the 550 EX at the same time?
Not with one receiver. PocketWizard does not recommend it. And for good reason. The camera always has a delay before releasing the shutter, so with a single receiver the flash would always trigger before the shutter could open. You need two receiver/transmitter pairs. One to trigger the camera and one to trigger the flash.
2: How is the PW connected to the camera? Can you mount the receiver in the hot shoe?
While the receiver can be mounted in the hot shoe of the camera, the shoe mount on the receiver is cold: there's no connection. The receiver needs to be connected to the N3 connector on the side of the camera, where a cable release normally goes. To connect the receiver to the camera, you need to use either a PocketWizard motor-drive
cable or a pre-trigger
cable. The difference is that the pre-trigger cable can simulate a half-press of the shutter button and eliminate the autofocus delay. The cables are pricy, to say the least. I believe you can get slightly cheaper cables from Paramount Cords
.
What I would like to do is set up a blind with the 20D and two 550EX and fire them remotely. It appears I would need two receivers, one for the camera, and one for the 550 master using the second 550 as a slave.
How close is my thinking?
Thanks
As mentioned above, you would not only need two receivers but also two transmitters. One transmitter would be connected to either the camera's hotshoe or the camera's PC sync port. The other tansmitter would be used to trigger to whole shebang. If you have a Sekonic lightmeter with the optional PocketWizard radio transmitter module, you can use it as the second transmitter.
The above applies to PocketWizard Plus units. You might be able to use a single PocketWizard MultiMAX receiver to trigger a camera and flash. This may be possible because a delay can be programmed between the triggering of the MultiMAX's two ports. You would have to know the camera's delay and the delay would have to be consistent. I've never done this, so I don't know if it's really possible.
